Title: Manufacture of nitride semiconductor wafer and element
Inventor: HASHIMOTO TADAAKI
IPC: H01L21/205
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To obtain the optimum nitriding condition by a simple method by specifying the nitriding time at a specific temperature in a nitriding process and, in addition, the ruggedness of AlN crystalline nuclei formed on the surface of a sapphire substrate. SOLUTION: A buffer layer 2 is deposited on a nitriding sapphire substrate 4 and a GaN crystalline layer 3 is grown on the layer 2. The nitriding time (t) (sec) of the substrate 4 is set at 4.7×10<-4> × exp (1.5×10<4> /T) when the nitriding temperature is T (k). In addition, the nitriding time (t) is set so that the ruggedness of AlN crystalline nuclei formed on the surface of the substrate 4 may not exceed 10 nm. Consequently, a crystalline layer 3 having high crystallinity can be obtained easily. When the temperature T is 1,000 deg.C, the nitriding time (t) is calculated to be about 62 seconds from the relation. Therefore, the productivity of a nitride semiconductor wafer 11 and, in addition, the crystallinity of a nitride semiconductor can be improved.

Title: Fuel injection valve
Inventor: MASAKI KENJI
IPC: F02M51/06
Filed: 1979-11-05
Abstract: PURPOSE: To improve fuel economy and suppress noise occurrence such as Diesel knockings by constructing the fuel injection valve such that the spring force is adjusted by the electromagnetic effect so that the fuel injection valve opening pressure can be varied corresponding to the driving conditions, thereby obtaining an improved combustion over a wide driving range.  
     CONSTITUTION: When an electromagnetic actuator 9 is not supplied with power, a nozzle needle 3 is pushed up at the time point of the fuel supplying pressure overcoming the baising force of a spring 6 so that the fuel injection is carried out. If the electromagnetic actuator 9 is supplied with power and a coil 12 is energized, an iron member 10 is attracted toward an electromagnet 11 and therefore, the nozzle needle 3 is pressed strongly against a valve seat 4 through a connecting rod 8 and a needle tapping screw 5. In order to open the injection valve, a pressure is required which is high enough to overcome the compound pressure of the spring 6 and the electromagnetic actuator 9. Therefore, the injection valve opening pressure should be inevitably increased accordingly.

IPC: F16L27/02
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a flexible coupler capable of preventing a pipe passage from being closed under its bent state and further preventing its outer appearance or workability from being deteriorated. SOLUTION: This flexible coupler 10 is constructed such that a coil spring 40 is stored in a hose 12, a coupler fitting 20 is connected to another pipe passage while the hose 12 is being bent. As a force for closing the pipe passage of the hose 12 is applied, the coil spring 40 may reinforce the hose 12 against this force from within the hose 12. Due to this fact, the pipe passage under its bent state is prevented from being closed and it is possible to hold a flow rate of fluid such as water flowing in the hose 12 or the like. In addition, since the coil spring 40 is inserted into the hose 12, the flexible coupler 10 is not made large in size and its outer appearance is also prevented from being deteriorated.  Further, since the spring 40 itself is flexible together with the hose 12, there is no possibility that a workability in connecting operation for another pipe passage is not deteriorated.
